MAINTENANCE
LITHIUM BATTERY – There is a lithium coin cell inside the unit to maintain the system
clock and settings. This is a common type 2032 battery available at most local outlets.
This battery typically lasts 2 years or more. If the unit powers up in the set date mode,
this indicates that the battery needs replacing. This battery can be accessed by
removing the 4 corner screws on the back of the unit. Then carefully slide the circuit
board assembly out of the case being careful to avoid pulling the interconnecting wires.
Replace the battery and slide the electronic assembly back into the housing being
careful to prevent the flat cable from being caught or pinched in the seal when the
screws are replaced. Tighten the screws to snug being careful not to strip the threads.
